It is equipped with a super small movement of only 23.7mm in diameter. The case is a Calatrava case, which is rare in Geneva, where many dress type designs such as fancy lugs are seen. The dial is a multi-colored and scaled design with a tachymeter (silver), telemeter (gold), and minute track (silver), which are rarely seen in Geneva. The black gilt dial with its intricate and detailed design and the Calatrava case with its beautiful flat bezel, despite its small size of 31mm in diameter, make this watch a precious gem with a presence that exceeds its size.
